In this episode of BrewFanatics TV, Josh and Dave decide to make 2 single gallon batches of the same Irish Red Ale recipe in order to see how changing the mash temperature changes the final outcome of the beer. They keep everything else (as close as possible) the same and set the high mash temperature to 150F and the low mash temperature to 140F. Check out the BrewFanatics “Brew Log” and see what changes they started seeing just after the fermentation.
